Yeah, we've known for a while that masks wouldn't do a whole lot when you're indoors with someone infected for hours at a time. Wearing a raincoat isn't going to keep you dry if you jump in a pool.
As I've said from the beginning, if wearing a mask reduced chances of transmission by even a few percent while out and about in public, it would be worth it to me. The cost is so low that even a small benefit was worthwhile.
There seems to be this idea that you're either in the camp that wears masks 24 hours a day and believes fervently that they're 100% effective or else you're in the group that believes they were always useless. The reality is somewhere in between. That masks likely have some utility in extending the exposure required for transmission and so have some utility in situations where you'll have relatively brief contact with others (e.g. at the store, waiting for a table in a restaurant, etc.)
That being said, I've followed the CDC guidance and am no longer masking as my area is not an area of high transmission. Also, people that mask outdoors or alone in their own car baffle me. That was just paranoia and not following any evidence or logic.
